In fact some magnetic compounds, called spin-glasses, are intrinsically disordered on a microscopic scale.

A review of the Statistical Mechanics approach to Random Optimization Problems

Depending on material details, some compounds show the coexistence of DSC and AFM9 while others exhibit microscopic separation of these two phases10 .

At the present time, the microscopic mechanism responsible for high-Tc FM is still quite controversial for the II-VI compounds, especially for Z nO based DMSs6 .

Based on density functional calculations, we report on the orbital order and microscopic magnetic model of FeNCN, a prototype compound for orbital-only models.

Orbital order and magnetism of FeNCN

The relationship between spin and orbital degrees of freedom in transition-metal compounds is well established on both phenomenological and microscopic levels.

Orbital order and magnetism of FeNCN

Whereas the ﬁssion valley in a macroscopic picture is several tens of MeV lower in energy than is the fusion valley, we ﬁnd in the macroscopic-microscopic picture that the ﬁssion valley is only about 5 MeV lower than the fusion valley for soft-fusion reactions leading to compound systems near Z = 110.

Microscopic Enhancement of Heavy-Element Production

To see beautiful images obtained with polarised microscope of such transition, look at Ref. where mesophases of 1,4"-pterphenyl-bis-2,3,4-tri-dodecyloxy-benzal-imine are investigated. This is a calamitic compound with a biaxial nematic phase.
